This is 911 GT3 levels of power.
With its naturally-aspirated flat-six, six-speed manual gearbox, and sharp handling, the Porsche 718 Cayman GT4 has all the ingredients of a perfect purist sports car. But that hasn't stopped Porsche from making it even better. We've known for a while now that Porsche is cooking up a hot RS version of the beloved Cayman GT4, and now a new report from Car and Driver has spilled some juicy details.
Like the regular Cayman GT4, the new RS will pack a naturally-aspirated 4.0-liter flat-six engine. While this unit produces 414 horsepower in the Cayman GT4, the hardcore RS version will increase the output to 500 hp according to the publication.
That's an impressive power bump considering that Porsche won't be using any turbocharging. This also means the GT4 RS will have the same output as the current Porsche 911 GT3. While a six-speed manual is the only transmission option for the 718 Cayman GT4, we're expecting the RS to come with a quick-shifting PDK transmission for faster lap times. 0-62 mph takes 4.2 seconds in the standard Cayman GT4 so the extra power in the RS could bring the sprint time below four seconds.
Tweaks to the chassis will also make the RS version lighter and stiffer than the regular GT4, making it more track-focused.
Spy shots have already shown Porsche preparing the hot GT4 RS. Early prototypes featured a massive rear wing, but more recent test cars were spotted with the same wing as the regular GT4. The rear side windows have been replaced with louvers to provide extra cooling for the engine.
As for when the Porsche Cayman GT4 RS will break cover, Car and Driver claims the reveal will happen in late 2021 or early 2022, but don't be surprised if the coronavirus pandemic affects Porsche's plans. Also expect the hardcore GT4 RS to command a higher price than the regular car. The Cayman GT4 starts at $99,200, but the RS version could cost around $130,000.
